Why can't DD sleep while being worn?

[newmamalizzy]

DD is 10 months old and pretty high strung.  She has an incredibly hard time relaxing enough to nap, so I've been trying to get her used to being worn when she's tired during the day.  It DOES tend to intensify her eye rubbing, but she can't seem to find a comfortable position to sleep in and ends up getting frustrated.  We have an Ergo and a homemade ring sling and this is true for both, although she can sometimes sleep in the Ergo if I have a coat zipped up over both of us.  Anyone have any tips for positioning an older baby so it's easy for them to sleep while being worn?

Have you tried the Ergo on the back and front?
